Features

  • In-place system calibration and online monitoring without disturbing process tubes with optional process valve actuator and test jacks
  • Ultrathin profile ideally suited for DIN rail mount reduces installation and calibration costs
  • High accuracy, two options; 0.25 % or 0.50 % of span
  • Extremely robust MEMS silicon sensor technology provides very high accuracy, sensitivity, stability, and durability
  • Calibrations traceable to SI units through national metrology institutes or accredited calibration laboratories
  • Front side accessible zero and span adjustment potentiometers Vaisala Differential Pressure Transmitter PDT102 offers ultra low pressure measurement for cleanroom control and monitoring applications. Operating environment Vaisala Differential Pressure Transmitter PDT102 is a high performance instrument designed primarily for life science and high technology cleanroom applications. The front panel includes zero and span adjustment potentiometers for convenient adjustment. The PDT102 transmitter is ideal for incorporating into the Vaisala viewLinc Continuous Monitoring System to measure and monitor the critical environmental parameters as required in regulated environments. Performance PDT102 offers very high accuracy, sensitivity and stability with two options for accuracy, 0.25% or 0.50% of span providing a highly reliable and repeatable measurement. The sensor uses a micro-machined, ultra-thin silicon diaphragm which provides inherent sensor repeatability and stability. The sensor enables precise measurement and control in high performance cleanrooms. The PDT102 transmitter is available with voltage output (3-wire) or current output (2-wire). Available options Online monitoring of PDT102 is simple using the optional process valve actuator and the front access test jacks. The front access test jacks provide online process reference signal or calibration signal without disconnecting power supply wiring. Measurements can be made using a standard multimeter.

Applications

PDT102 is designed for use in critical monitoring of cleanrooms for pharmaceutical, biotechnology, medical device, and semiconductor controlled manufacturing environments.
